SMART error (Temperature) detected on host

MtK · Nov 30, 2013

Hey,
I just got my system up and running on a Fractal Defin Mini with 6 drives.
Ran the first S.M.A.R.T (before setting a pool) just to see everything is OK, but got:

Code:

Device: /dev/ada0, Temperature 40 Celsius reached critical limit of 40 Celsius (Min/Max ??/40)

(on all 6 drives)

fans are working and system temp looks ok.

is that normal?

The optimal temperature for HDDs is 30-40°C, anything over 40°C will see increased failure rates. You should check the smart attributes to see how hot they get in normal operation. Keep in mind that they tend to heat up quite a lot when you put strain on them (scrubs, read/write operations).

I'm also running into heat problems in summer, since my case is very compact and additionally I've got a passively cooled CPU in there. I'll definitely need to take care of that before next summer.

the system is completely new, and the system just booted.
as I mentioned in the post, I didn't even create a pool yet, so there is no real stress on the drives..

What is the output of smartctl -a /dev/ada0 (in [code]-tags please to keep the formatting).

Yeah, it's running at 39°C right now. Since you have got a WD Blue with 7200RPM it will run hotter than a Green model.

I'd keep an eye on the temperatures and see how they go while a scrub is in progress. If it regularly exceeds 45°C I'd look into improving the cooling. Remember to properly set up smart emails and reporting, so that you get a warning if a drive decides to fail.

So if I may opine.

The case you have, it comes with two 120mm cheapo fans. But it has room for 4 fans, and one or more of those mount point, if memory serves, will handle a 140mm fan, and these can move as much as 50% more air.

Have you considered investing in maximizing your fans? i.e, start with taken any unused fan mount points, and put fans on it? "Cougar Vortex" is an exception fan, available as 140 or 120mm models, for under $20.

You're at a borderline point...39-40C...that suggests to me that you can benefit a lot by incremental improvements like having more/better fans.

Also, 40C is not the end of the world. You can go in there and reset the "critical" temp to 45 or something so you don't have the warning annoying you.

I have a plan of adding fans, yes.
but this is a newly installed machine and thought it'd be in a better shape before I will be forced to add more fans...

DrKK · Nov 30, 2013

Well, you've got six 7200 RPM drives in that case, sir, presumably near the edges of the case, and hence near the fluid dynamic stagnation points of the air. You have plenty of low cost options to solve this cooling problem.

And like I said, you're really close to having an OK thermal situation. It's just a few degrees hot. A couple more fans, of the right size and type, and we'll get this.

What is the output of smartctl -a /dev/ada0 (in [code]-tags please to keep the formatting).

Running smartctl -l scttemp /dev/ada0 will give you much more detailed temperature info including the current power cycle & lifetime max/min values and a temperature graph. My WD REDs log the temperature every minute and keep the data for 8 hours.

according to this, I really (!) need a fan:

I didn't say I don't need.
but take a look at my last post, it's ada5 which doesn't have a direct fan on it...

DrKK · Nov 30, 2013

That's funny that my drives got down to 18C or so at times.

I guess we know how warm I keep my house. :)

According to the google study (figures 4 & 5), such low temperateures aren't exactly beneficial either: "In fact, there is a clear trend showing that lower temperatures are associated with higher failure rates."

DrKK · Nov 30, 2013

You're absolutely right, and Cyberjock and I were already discussing this at length weeks ago about my drive temps being "too low"!!!

But meh, what am I going to do? Put a heater in there? And in any case, the failure curve for "low" temperature is when the drive is first put into service. Low temperatures don't seem to matter once the drive has been in service for a certain number of hours.

Whereas, high temperatures are always bad, at any time, in the drive's life.

Dusan · Dec 1, 2013

Everybody else is adding fans, so maybe remove one? :) Or lower the RPM?
